[0039] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows: First, assemble the loading structure 1, fix the bottom plate 11 below the base 12 by the first bolt 13, then fix the box body 14 on the overload base 12 by the second bolt 15, and at the same time, buckle the box cover 16 on the top of the box body 14 by the second bolt 15 to form a sealed box body 14, which can be loaded with additives; insert the nozzle 18 upside down into the pipe mouth and screw it, and use the conical nozzle 18 as a funnel for injection, put the nozzle 18 on the pipe mouth and screw it to place it, and use the handle 17 to pour it, and use the sealing cover 19 to screw on the nozzle 18 to seal it; After the additive is loaded, before use, it can be placed horizontally on the ground and manually pulled the driving rod 24. One end of the driving rod 24 passes through the telescopic opening of the box body 14 and moves outward. It will be meshed with the first gear 22 in the dustproof unit through the teeth, driving the first driving rod 21 to rotate through the first bearing and the second bearing. The first driving rod 21 will drive the fan blade 23 to stir the middle part of the bottom end of the interior; At the same time, the pulling of the driving rod 24 drives the two scrapers 25 to scrape the sediment from the lower wall of the box 14, that is, the upper wall of the base 12. The scrapers 25 scrape the sediment from the front and rear sides of the first gear 22, and float and mix them with the driving pull of the fan blades 23. As the driving rod 24 is pushed and pulled back and forth, the first gear 22 drives the first driving rod 21 to rotate back and forth; due to the relative engagement of the three bevel gears 33, the second driving rod 32 in the mixing unit 3 can be driven to rotate on the shaft frame 31. Through the L-shaped design of the second driving rod 32 and the transmission rod 35 movably connected between the driving rod and the lifting rod 34, the eccentric reciprocating motion can be realized to drive the lifting rod 34 to move up and down through the telescopic hole of the base 12; The two lifting rods 34 can be lifted and lowered alternately or synchronously. When the lifting rod 34 moves up and down, it will pull the protruding middle part of the stirring shaft 36 through the driving frame 37. The middle part of the stirring shaft 36 can move a certain distance on the driving frame 37, thereby driving the stirring shaft 36 to rotate, and finally driving the stirring plate 38 to flip and swing back and forth, further stirring the suspended sediment to promote mixing, ensuring the miscibility and concentration of the additive inside, and preventing it from affecting use.

[0040] After the additives are loaded, clean water can be injected to clean the loading box in the same way as the above operation.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
